MARYLAND GEOLOGICAL SUBVEY 33 noted certain well-defined terraces which Avere distributed over the entireregion, and spoke of them as follows: There is a practically continuous series of terraces and beach marksalong the fall line from the Eoanoke to the terminal moraine—a seriesof shore lines as distinctive and unmistakable as those circumscribing thevalleys of the extinct lakes of the Great Basin, of India, of northernArabia, or of the partially ice-bound basins of Minnesota, Michigan,Ohio, and New York, though they are generally more profoundly modifiedby erosion and are frequently concealed by forests. These shore linesembody an easily interpreted record of geologic vicissitude which coin-cides in every detail with that of the Columbia deposits. They aresometimes carved out of the sub-terrane, but are generally built of theloam, sand, and gravel of which the Columbia formation consists andare evide
